This can't be happening again....

In March my husband and I suffered our first miscarriage. We waited a few months before trying again and on our 3rd cycle of clomid in July we were able to get pregnant again. Well today I am 7w2d and  I started spotting pink blood and having tiny little cramps..of course I couldn't help but think the worse. Everything stopped for about an hour and then it started again but with bright red blood and worse cramps. I have my 1st prenatal appointment Thursday but I will be calling the office first thing tomorrow to see if they can take me tomorrow. I just can't help but think the worse, and I don't know how I can do this again...with my first we found out my SIL was 4 days behind me and had no issues so that was hard and just yesterday we found out friends of ours are also expecting and once again, a week behind me. I can't help but think how unfair this all is. This makes me want to just give up. 4 years of trying to finally get pregnant twice and then to loose the 1st and potentially loose the 2nd. Sorry for the rant, we hadn't told many people yet so I feel I can only really talk about this here....hoping I'm blowing this all up and I find out tomorrow or Thursday that baby is fine...prayers needed!
